1. JBL GTO629: Best Overall
We researched and compared the JBL GTO629 and found it offers a balanced sound profile with enhanced bass thanks to the Plus One woofer cone. Owner feedback consistently praises its clarity even at highway speeds, and the edge-driven tweeter reduces harshness. The 2-ohm impedance allows higher power output from compatible amplifiers, making it a strong upgrade for those who already have or plan to add an amp.
However, without an amplifier, the GTO629 may sound underwhelming compared to higher-sensitivity models. Riders who want a simple head-unit-only upgrade should consider higher-sensitivity options. This speaker is best for those willing to invest in a full system for maximum audio quality.
- Plus One woofer cone delivers more surface area for deeper bass
- Edge-driven tweeter provides smooth high frequencies
- Weather-resistant design with rubber surround for outdoor durability
Pros: Excellent clarity at high volume; Easy drop-in fit for Street Glide fairings
Cons: Requires an amplifier to reach full potential
2. Rockford Fosgate T1650: Best High-Output
We researched and compared the Rockford Fosgate T1650 and found it to be a top-tier component system that delivers outstanding sound quality. The separate tweeter and crossover allow precise tuning, and owner feedback highlights the clear, powerful output that cuts through wind noise. The VAST surround increases effective cone area for better low-end response without increasing mounting depth.
Installation is more involved than coaxial speakers, requiring routing wires and mounting tweeters. Riders seeking a simple swap may prefer a coaxial design. This set is ideal for audio enthusiasts who prioritize soundstage and are comfortable with a moderate DIY install.
- Integrated T1 tweeter with VAST technology for wide soundstage
- Vertical Attach Surround Technique increases cone area
- Includes external crossover for precise frequency separation
Pros: Exceptional high-frequency detail and imaging; Built to withstand harsh weather and vibration
Cons: More complex installation due to separate crossover and tweeter
3. Hertz HCX 165: Best Plug-and-Play
We researched and compared the Hertz HCX 165 and found it excels as a direct replacement for factory speakers. With 93dB sensitivity, it produces ample volume from the stock radio, and owner feedback reports noticeable improvement in clarity and midrange. The Tetolon tweeter provides a smooth top end that avoids listener fatigue on long rides.
However, bass output is modest, and riders seeking deep low frequencies will need to add a subwoofer or amplifier. This speaker is best for those who want a quick, hassle-free upgrade without wiring changes.
- High sensitivity (93dB) works well with stock head unit
- Tetolon tweeter for detailed highs without harshness
- Weather-resistant cone and rubber surround
Pros: Direct fit, no modification needed; Great sound improvement over stock without amplifier
Cons: Limited bass compared to amplified systems
4. Polk Audio MM652: Best Marine Rated
We researched and compared the Polk Audio MM652 and found it stands out for its marine certification, making it highly resistant to water, salt, and UV exposure. Owner feedback from riders in wet or coastal climates praises its longevity. The sound is clean and balanced, though it doesn’t reach the same peak loudness as some rivals.
Riders who prioritize extreme volume over weather resistance may find other options better suited. This speaker is ideal for those who ride in all conditions and want long-term reliability.
- UV-stabilized components and stainless steel hardware
- Dynamic Balance motor structure for low distortion
- Polypropylene cone with butyl rubber surround
Pros: Excellent durability against moisture and UV; Clear, balanced sound at moderate volumes
Cons: Slightly underwhelming maximum volume compared to competitors
5. Infinity Kappa 62IX: Best for Clarity
We researched and compared the Infinity Kappa 62IX and found its sound quality to be exceptional for the price, with a wide soundstage and crisp highs. The Plus One cone design helps bass response. Owner feedback often highlights the clarity, especially for vocals and instruments.
However, some users report that the tweeter can be prone to failure in heavy rain or extreme temperatures, and the 3-ohm impedance may not be optimal for all amplifiers. This speaker is best for riders who prioritize audio fidelity and ride primarily in fair weather.
- Plus One woofer cone for increased bass output
- Edge-driven textile tweeter for smooth highs
- High-resolution polymer tweeter with waveguide
Pros: Very detailed and clear midrange and highs; Good sensitivity for use with stock head units
Cons: Durability concerns reported by some owners in harsh weather
6. Kenwood KFC-1666S: Best Budget
We researched and compared the Kenwood KFC-1666S and found it to be a solid entry-level upgrade. Owner feedback notes it provides a noticeable improvement over stock speakers, with better clarity and slightly more bass. The included grille is a nice touch for protection.
However, the low RMS rating means it cannot handle high power without distortion, and the materials are less durable than marine-rated alternatives. This speaker is best for budget-conscious riders who want an improvement without breaking the bank.
- Polypropylene cone with rubber surround
- 1-inch balanced dome tweeter
- Grille included for protection
Pros: Very affordable, good value for the price; Simple installation, fits many Street Glide models
Cons: Limited power handling, distortion at high volume; Build quality not as robust as premium options
7. Alpine S-S65: Best Value
We researched and compared the Alpine S-S65 and found it offers excellent value for riders seeking a mid-range upgrade. Owner feedback praises its natural sound signature and good output when paired with an amplifier. The HAMR surround allows deeper bass than typical coaxial speakers.
However, the lack of marine certification means it may not hold up as well in constant rain or extreme humidity. Riders in dry climates or who store their bike indoors will find this a great choice for the price.
- Alpine HAMR surround for increased cone excursion
- Silk dome tweeter for natural sound
- Multi-fit mounting system for easy installation
Pros: Good balance of price and performance; Clear, natural sound across frequencies
Cons: Not as weather-resistant as marine-rated speakers
Frequently Asked Questions
What size speakers fit a Harley Davidson Street Glide?
The Street Glide typically uses 6.5-inch speakers in the fairing and saddlebag locations. Most aftermarket 6.5-inch speakers will fit with an adapter or direct replacement, but always check depth clearance as some models require spacers.
Do I need an amplifier for new speakers on my Street Glide?
Not necessarily. High-sensitivity speakers (92dB or higher) can work well with the stock head unit. However, an amplifier will unlock the full potential of most aftermarket speakers, providing cleaner sound at higher volumes without distortion.
Are marine-rated speakers necessary for a motorcycle?
Marine-rated speakers offer better protection against moisture, UV, and vibration, making them a smart choice for riders who frequently ride in rain or live in humid areas. For fair-weather riders, standard speakers may suffice.
Can I install speakers myself on a Street Glide?
Many riders successfully install speakers themselves. The fairing speakers are usually straightforward with basic tools and wiring knowledge. Component systems with separate crossovers and tweeters are more complex. Always disconnect the battery before starting.
Will aftermarket speakers affect the bike's electrical system?
Most aftermarket speakers are designed to be compatible with the bike’s electrical system. However, high-power speakers and amplifiers may draw more current, so ensure your charging system can handle the load. Upgrading the battery or stator might be necessary for extreme systems.
